Array substrate, display panel and display device

An array substrate comprising:

• a display region;
• and
• a frame region surrounding the display region, the frame region comprising:
• a plurality of bridge-type pressure sensing units, each of the plurality of bridge-type pressure sensing units comprising a bridge electrode, a first power supply line electrically connected to a power supply terminal of the bridge electrode, and a detection line electrically connected to a detection terminal of the bridge electrode;
• a plurality of first heat conductive sheets, in a one-to-one correspondence to the plurality of bridge-type sensing units, wherein each of the plurality of first heat conductive sheets is arranged opposite to the corresponding bridge electrode, and a vertical projection of each of the plurality of first heat conductive sheets on the corresponding bridge electrode covers the corresponding bridge electrode;
• and
• a plurality of second heat conductive sheets, in a one-to-one correspondence to the plurality of the bridge-type sensing units, wherein each of the plurality of second heat conductive sheets is arranged at a layer different from a layer where the corresponding bridge electrode is arranged, and arranged on a side of the corresponding bridge electrode away from the plurality of first heat conductive sheets, and a vertical projection of each of the plurality of second heat conductive sheets on the corresponding bridge electrode covers the corresponding bridge electrode.
